Ko te tinei auau teitei he tukanga whakapakeke mata e whakamahi ana i te aukume hikohiko hei whakamahana tere i te mata o te taputapu ki tōna pāmahana tino nui (te nuinga o te 800–950°C), ā, muri iho ka tinei tonu ki te wai, ki te hinu rānei. Ka hua ake he paparanga martensitic whakapakeke e whakanui ana i te pakeke o te mata me te ātete ki te kakahu me te kore e whakararu i te pakari o te matua o te taputapu. I te mea e hiahia ana ngā ahumahi ki te mahi teitei ake i roto i ngā tono taipana kiato, teitei, kua noho ko ngā taputapu tinei auau teitei hei mea nui i roto i ngā taputapu motuka, keri, pūngao, me te tika.

Ngā Painga Mahi Matua

1. Tino pakari te mata me te ātete ki te kakahu
Mā te whakamahana tere i te mata o te niho taputapu me te tinei, ka puta he paparanga martensitic kua whakapakeketia me te pakeke o te HRC 55–62 (e kitea whānuitia ana i roto i te maitai 40Cr, 42CrMo rānei).

• Ka piki ake te ātete ki te kakahu mā te neke atu i te 50%

• Ko te pakaru o te mata he 30–50% noa iho, ki te whakaritea ki ngā taputapu tuku iho kāore i rongoatia.

• He pai mō ngā taiao waku nui pērā i ngā pouaka miihini taumaha me ngā mīhini keri

2. Kaha Nui o te Ngenge
Ka puta te ahotea toenga pēhi i roto i te paparanga kua mārō te tukanga tinei, ka pehi i te tīmatanga me te tipu o ngā kapiti mata.

• Ka piki ake te rohe ngenge mā te 20–30%

• Hei tauira, ka taea e ngā taputapu matua o te tāhū hau i hangaia mai i te 42CrMo te whakatutuki i te roanga mahi o te 20 tau.

3. Te Pūmau o te Pakari Matua
Ko te paparanga o waho anake ka whakapakeketia (ko te nuinga o te wā he 0.2–5mm), ko te uho ia ka noho ngāwari, ka ātete hoki ki te pānga.

• Mā tēnei āhuatanga takirua ka mau te mata, ka ātete hoki ki te pakaru i raro i ngā kawenga ru.

• He whānuitia te whakamahinga i roto i ngā taputapu toki motuka me ngā wāhanga utaina pānga

Ngā Painga o te Whakahaere Tukanga

1. Te Whakapakari Ā-Rohe Tika
Ka taea e te tukanga te aro ki ngā niho takitahi, ki ngā rohe motuhake rānei i runga i te mata o te taputapu, kia pai ai mō ngā kōtaha uaua pēnei i ngā taputapu aorangi me ngā āhua kore-paerewa.

• Ka taea te whakarerekē i te hohonutanga mā te auau, te mana, me te wā

• Ka taea te whakahaere motuhake i te tono me te iti o te whakarerekētanga

2. Teitei o te Whai Hua me te Penapena Pūngao
E torutoru hēkona ki te tekau hēkona noa iho te roa o te tukanga katoa, e whakaiti ana i te whakapaunga pūngao mā te 30% ki te whakataurite ki ngā tikanga tuku iho.

• Hototahi ki ngā raina whakaputa aunoa e whakamahi ana i te whakahaere karetao

• He pai mō te hanga nui

3. He iti te whakarerekētanga
Mā te whakamahana tere me te ā-rohe ka whakaitihia te hē o te pāmahana.

• Ka taea te whakahaere i te rerekētanga porowhita i roto i te ≤0.01 mm mō ngā taputapu tika (hei tauira, ngā taputapu porowhita CNC)

• Ahakoa he iti ake te rerekētanga o te ahua o te tinei laser, he iti ake te utu o te tinei auau teitei, ā, he nui ake te ngāwari o te hōhonutanga.

Te Whai Hua o ngā Rauemi me te Utu

1. Hototahitanga Rauemi Whānui
E pā ana ki ngā maitai waro waenga me te waro teitei, me ngā maitai koranu he ≥0.35% te ihirangi waro, pērā i te S45C, 40Cr, me te 42CrMo.

• Tautoko i te whānuitanga o ngā tono taputapu ahumahi

2. Te Ōwehenga Mahi Utu Pai Rawa
Mā te tinei auau teitei ka taea te whakamahi i ngā rauemi iti ake te utu (hei tauira, te whakakapi i te 40CrNiMoA), ka whakaitihia ngā utu rauemi mā te 20–30%.

• He iti ake te hiahia mō te miihini i muri i te maimoatanga

• Ka whakapai ake ngā huringa whakaputa poto i te whai huatanga o te hanga katoa

Ngā tono noa

He whānuitia te whakamahinga o ngā taputapu tinei auau teitei puta noa i ngā ahumahi maha nā te mea he tino pakari te mata, he ātete ki te kakahu, he kaha hoki ki te ngenge. I roto i tete rāngai motuka, e whakamahia ana ēnei i roto i ngā taputapu tuku i hangaia mai i te maitai 40Cr, ka taea te roa ki te 150,000 kiromita, tae atu ki ngā porowhita miihini mahi teitei. Mōmīhini taumaha, ka whakamahia ēnei taputapu ki ngā toki kuru keri ina eke te pakeke o te mata ki te HRC 52, ā, neke atu i te 450 MPa te kaha o te piko me te ngenge.

In taputapu tino tika, pērā i ngā taputapu mīhini CNC, ka taea e ngā taputapu porotaka i hangaia ki te 42CrMo te mahi mō ngā hāora neke atu i te 5,000 me te kore e rerekē te āhua. He wāhanga matua anō hoki ēnei i roto i ngā pou matua o te tāpine hau, he mea nui te pono me te roa o te mahi. I roto i ngā mara ote kawe tereina me te karetao, ka whakamahia te tinei auau teitei hei whakarei ake i ngā pūnaha pouaka miihini i roto i ngā tereina tere me ngā karetao, tae atu ki te whakapakari i ngā pūnaha tīwiri roera aorangi

Te Tirohanga ā-Mārama

Nā te whakakotahitanga o te mata mārō me te matua pakari, kāore e taea te whakakapi i ngā taputapu tineia auau teitei i roto i ngā tono kawenga nui, tere teitei, me te tino tika. Nā te ngāwari o te tukanga, te iti o te hē, me te whai hua o te utu, kei te noho tonu hei otinga pai i roto i ngā rāngai motuka, taputapu hiko, me ngā mīhini tino tika.

Ka arotahi ngā whanaketanga ā muri ake nei ki:

• Te whakauru i ngā mana whakahaere matihiko hei whakapai ake i te tika o te tukanga

• Te whakatairanga i ngā tikanga poto, pai mō te taiao hei whakaiti i te whakamahinga pūngao me ngā tukunga
